Question

calculati numerele c, d e , f unde c=a+b, d=a-b, e=c+d, f=c-dstiind ca
a=+6;b=+3
a=+4;b=-7
a=+5;b=-3
a=-7;b=-10 va rrrrrrrrrrrrrroooooooooooooooooooooogggggggggggggggggggg din suffffflllllletttttttttttttttttttt

Answer 1

c=a+b.........c=+6+3=9
c=a+b..........c=+4+(-7)=+4-7=-3
c=a+b...........c=+5+(-3)=+5-3=+2
c=a+b............c=-7+(-10)=-7-10=-17

d=a-b.............d=+6-(+3)=6-3=3
d=a-b............d=4-(-7)=4+7=11
d=a-b...............d=+5-(-3)=+5+3=8
d=a-b.................d=-7-(-10)=-7+10=3

e=c+d..............e=9+3=12

f=c-d.................f=9-3=3
